how long Arowana could survive in power out? (without electricity)

[Tin foil]

In my country random power cuts may be occur due to many reasons such as break down of stations,lines,maintenance etc...so I want to know how long Arowana could survive without aeration and filtration in it's tank?
My tank size - 8ft x 1.5ft x 1.5ft
Desired Arowana size to buy - 5"-10"

the usual power cut may last up to 2-4hrs

It will be fine, I got power out almost entire day without warning from Power Company while I'm at work, nothing die and my fish seem have 0 effect without power (Most my tank are not overstocked and mostly single species for each tank)

Room temp may be an issue in colder months, but only if the power were to go out for 6+ hours. water holds heat

Welcome to mfk, a tank of your size will remain ok for many hours, mine went for 16 hours without electricity and no losses. If it is a problem in your part of the world, you may want to invest in a battery powered air pump or an inverter.
